Description
technical field [0001] The invention relates to the technical field of agricultural machinery measurement, in particular to an agricultural machinery steering angle measurement device. Background technique [0002] With the introduction and continuous development of precision agriculture and smart agriculture, automatic navigation has received more and more attention in agricultural machinery. The unmanned operation of agricultural machinery can not only reduce the labor intensity of operators, but also improve the accuracy of farmland operations. Automatic steering is one of the necessary functions of automatic navigation agricultural machinery, and the first thing to realize automatic steering is to measure the steering angle of the agricultural machinery. [0003] Existing instruments for measuring the steering angle mainly include angle encoders, resistive angle sensors, and the like. The use of an angle encoder requires a matching connecting rod structure to measure th...
